ARM: dts: qcom: keep VDD_MMCX and VDD_MXC supplies always on for Sun RUMI

Browse Source 
Set regulator-always-on for VDD_MMCX and VDD_MXC on Sun
RUMI. This ensures that clock controller register values
are maintained since RUMI isn't simulating register
retention across VDD_MMCX or VDD_MXC power collapse.
